Britney also posted a loving message to her estranged sons Jayden and Sean Preston – who she shares with ex-husband Kevin Federline.

She said: “To both of my boys … I love you … I would die for you !!! Godspeed my precious hearts !!! I would give anything just to touch your face !!! I send my love … Mamasita.”

And, Britney revealed that her husband Sam Asghari. 28, surprised her with a cake and sweetly sang ‘Happy Birthday’ to her.

She shared a video and wrote: “My husband surprised me !!! I’m sick with the flu and he came downstairs … he was pretty f****** smooth !!!! I love you !!!! It’s Mr. and Mrs. Asghari !!!
